#### Technical details
- Built on Jetpack compose and kotlin multiplatform libraries ktor and sqldelight (although the project is not currently setup to be multiplatform until needed).
- Greenfield matrix SDK implementation, focus on separation, testability and parallelisation.
- Heavily optimised build script, clean _cacheless_ builds are sub 10 seconds with a warmed up gradle daemon.
- Avoids code generation where possible in favour of build speed, this mainly means manual DI.
- A pure kotlin test harness to allow for critical flow assertions [Smoke Tests](https://github.com/ouchadam/small-talk/blob/main/test-harness/src/test/kotlin/SmokeTest.kt), currently Linux x86-64 only.
- Messages once decrypted are stored as plain text within `SmallTalk's` database. _Always encrypted messages_ comes at the cost of performance and limits features like local search. If maximum security is your number priority, `SmallTalk` is not the best option. This database is not easily accessed without rooting or external hardware.
- (Not yet implemented and may be configurable) Images once decrypted are stored in their plain form within the devices media directories, organised by room metadata.
- Push notifications contain no sensitive data by using the [event_id_only](https://github.com/ouchadam/small-talk/blob/main/matrix/services/push/src/main/kotlin/app/dapk/st/matrix/push/internal/RegisterPushUseCase.kt#L31) configuration. Push notifications are used as a _push to sync_ mechanism, where the on device sync fetches the actual contents.
- Passwords are **NEVER** stored within `SmallTalk`.
-`SmallTalk` does not explicitly talk to servers other than your home-server or track what you do. __*__
- __*__ There is no `SmallTalk` server capturing data from the application however the Google variant likely includes transitive telemetrics through the use of `Firebase` and `Google Play Services` integrations.
-`SmallTalk` is completely free and will never feature adverts or paid app features.

`SmallTalk` comes in two flavours, `Google` and `FOSS`
##### Google
- Available through the [Google Play Store](https://play.google.com/store/apps/details?id=app.dapk.st) and [Github Releases](https://github.com/ouchadam/small-talk/releases).
- Automatic crash and non fatal error tracking via [Firebase Crashlytics](https://firebase.google.com/products/crashlytics).
- Push notifications provided through [Firebase Cloud Messaging](https://firebase.google.com/docs/cloud-messaging).
- Available through a [self hosted F-Droid Repository](https://ouchadam.github.io/fdroid-repository/repo/) and [Github Releases](https://github.com/ouchadam/small-talk/releases).
- No Google or Firebase services (and their transitive telemetrics).
- No crash tracking.
- No push notifications by default, a separate [UnifiedPush](https://unifiedpush.org/) [distributor](https://unifiedpush.org/users/distributors/) is required.
